CAR-STARTER.

SPECIFICATION forming part of Letters Patent No. 279,049, dated June 5,1883,

Application filed March 26, 1883. (N0 model.)

To all whom it may concern Be it known that I, Emil U'rz, ofHalstead, inthe county of Harvey and State of Kansas, have invented certain new'anduseful Improvements in Car-Starters; andldohereby declare that thefollowing is afull, clear, and exact description of the invention, whichwill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, whichform a part of this specification.

My invention has relation to car-starters of that class wherein themomentum of the car operates through the medium of mechanism connectedto the axle to create a tension inaspiral spring at the moment ofstopping the car, the tension of the spring being brought intorequisition to start the car when the brakes are released.

My invention consists in the construction and combination of partshereinafter fully set forth, whereby the object above suggested isattained.

Referring to the accompanying drawing, A designates a spiral spring,which is attached at one end to a suitable part of the car-frame or itsplatform.

B designates a pitman-bar, journaled at one end on one of the axles, A,of the car, and having a slotted head, B, at the other end,whichembraces an eccentric, c, mounted on and keyed to the next adjacentaxle, A". Upon the axle A is also loosely mounted a combinationwheel, D,having on its periphery two parall'el divisions, the one being groovedaround its entire circumference and the other toothed,like aratchet-wheel, and about half-way around. The toothed portion of theperiphery of the wheel D is again dividedinto two parallel rows, g andg,whose teeth point, respectively, in opposite directions.Acrossthegroovedportion of the periphery of the wheelDis pivoted, at

one point of its circumference, the swivel d, by

means of apivot, b,which also serves as an axle for the small roller oreccentric r, the latter having an irregularly-cut face, a segment beingcut there from and roughened, wings a" r being formed diametricallyopposite each other on the face of said roller 1-. The swivel disconnected with the spiral spring Aby means of a chain or rope, d, Theroller 9- is journaled between the arms of swivel d, and the roller ismaintained in. position with its segmented face to one side and one ofits roughened surfaces in contact with the roughened surface of a wheel,E,'made fast to the aXleA of the car: The wheel D has an opening formedin its grooved periphery at 'd", through which projects one side ofroller '1' in such manner that said roller will come into con tact withand bind upon the surface of wheel E at the end of its movement by meansof springs 00 at, situated between said roller and the yoke of theswivel.

f f and f j are apair of duplexlever-hooks, facing each other andpivoted to the upper side of the head B ofthe pitman B, on oppositeends, respectively, of said head, the two sets of hooks serving to workthe device on either side, according to the direction in which the caris moving.

Gonfining the description now to the duplex lever-hooksff, a rope orchain, a, is attached to the lever-hookf, and, passing around a roller011 the end of hook f, is attached to a spring-bar, i, which is securedto and depends from the car-frame. Thence the spring-bar 17 is connectedby a rope or chain, K,with brakeshaft 7:. This chain K winds around theshaft in a direction opposite to which the brakecont-racting chain windsaround the same shaft, so that when the latter is tightened the otherwill be loosened, and vice versa.

So long 'as r the brakes are off the lever-hooks are disengaged andidle; but when the brakes are put on, and at the first full turn of theshaft, the lever-hooksfj" will bebrought into contact with the teeth 9of the ratchet on wheel D and en gage the same. The pitmairhead B, beingthen worked up and down by the movement of eccentric C, will cause saidhooks to turn the roller D and with it the swivel (7, thereby distendingthe spring A and continuing such distention until the car comes to afullstop, thus in effect storing up the momentum of the car, to be afterwardused in starting the same; Now, when the brakes are loosened and thetension on chain K and rope a is relieved, the leverhooks f f aredisengagedfrom the ratchet=teeth r 9. Consequently the spring A, beingno longer restrained, is allowed to exert its contractile force. Suchcontractile force is, through the roller '2', brought to bear upon thewheel E,

which is drawn around, carrying with it the wheel D. Now, as the wheel Eis keyed to the axle A the latter is also turned, and with it thecar-wheels moimted thereon. The operation just'described, involving theuse of hooks f f and their connections a, K, and i, is brought intorequisition when the car is moving in the opposite direction. In the latter case the chain K is attached to a brake; shaft at the other end ofthe car, while the levers f f engage with the ratchet-wheel 9, givingthe wheel D a motion the reverse of that prex'iously described. Underthis motion the roller is completely invert-ed, while the swivel dadapts itsef to such inversion. Upon releasing the hooks f f the wheel Eis drawn around and the axle and ear-wheel correspondingly rotated.

That I claim as my invention is- 1. In a car-starting attachment,'tliecombination, with the axle A having the wheel E and eccentric O fastthereon, of the grooved and toothed wheel D, roller 1', swiveled towheelD, chain or cable H and -spring A, and the pitman B B, carrying theduplex levers f f, 2 coupled or connected to the brake-shaft, sub 7stantially as set forth.

2. In a car-starting attachment, the combination, with the axle A of aneccentric, C, a pitman, B B, spring A, and mechanism, substantially asdescribed, whereby said spring is distended through the operation of thepitman and eccentric.

The combination, ina car-starter, of the pitman 13 Bend the duplexlevers ff, sub 35 stantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in pres ence of two witnesses.
